This is a generous yardstick. I could have picked French literature, full of slim little books, but I intentionally went with Russian novels and their reputation for ponderousness.
In Goncharov's Oblomov, for example, the title character spends the first hundred pages just getting out of bed. If you open that tweet in a browser, you'll see the page is 900 KB big.
That's almost 100 KB more than the full text of The Master and Margarita, Bulgakov’s funny and enigmatic novel about the Devil visiting Moscow with his retinue (complete with a giant cat!) during the Great Purge of 1937, intercut with an odd vision of the life of Pontius Pilate, Jesus Christ, and the devoted but unreliable apostle Matthew.
For a single tweet.
Or consider this 400-word-long Medium article on bloat, which includes the sentence:
"Teams that don’t understand who they’re building for, and why, are prone to make bloated products."
The Medium team has somehow made this nugget of thought require 1.2 megabytes. That's longer than Crime and Punishment, Dostoyevsky’s psychological thriller about an impoverished student who fills his head with thoughts of Napoleon and talks himself into murdering an elderly money lender.
Racked by guilt, so rattled by his crime that he even forgets to grab the money, Raskolnikov finds himself pursued in a cat-and-mouse game by a clever prosecutor and finds redemption in the unlikely love of a saintly prostitute.
Dostoevski wrote this all by hand, by candlelight, with a goddamned feather.
